Three year retrospective analysis of computer-assisted emergency dental triage in Tasmania, Australia.

Introduction: Tasmania is Australia's smallest state measuring approximately 68,000 km2 and separated (by approximately 240 km of ocean) from the mainland of Australia, at the south-east corner of the continent. The total resident population of Tasmania is approximately 500,000 people with the greatest population density in the capital city, Hobart. Adult dental care is subsidised for socioeconomically disadvantaged people and are provided through the State government dental clinics.

Visual information processing speed in hypnotized and nonhypnotized subjects.

Using a backward-masking paradigm with a bias-free and ceiling-free psychophysical task, we tested hypnotized and control subjects for speed of visual information processing. Approximately half of each group received visual imagery suggestions in an attempt to influence attention. Imagery produced no significant differential effect.

Visual recognition memory for binary pictures: another look.

Recognition memory for matrices of 0s and 1s was examined as a function of the number of elements (complexity) and density of those elements within the matrix. It was found that with greater density and lesser complexity, recognition performance improved. This result contradicts an earlier finding of Green and Purohit, who concluded that the more complicated matrices led to better performance.
